Bottom belt coal sweeper with deviation rectifying function

The bottom belt coal sweeper with the deviation rectifying function comprises a supporting plate and a deviation rectifying mechanism, the deviation rectifying mechanism is arranged on one side of the surface of the supporting plate, and a cleaning mechanism is arranged on one side of the surface of the supporting plate. According to the bottom belt coal sweeper with the deviation rectifying function, through the arrangement of the deviation rectifying mechanism, when a conveying belt deviates in the coal mine conveying process, a driving motor can be started, the driving motor drives a forward and reverse screw rod to rotate in a sliding groove, and when the forward and reverse screw rod rotates, sliding blocks move close to each other or away from each other; at the moment, the sliding block drives the stand column to move, according to the field operation environment, after the sliding block slides to a proper position, the stand column is made to move to a proper position through the clamping column conne
